Hi,is it possible to configure Postfix to send an interim non-delivery report? I'm using the default settings so Postfix will try to deliver a mail for 5 days. So if a mail fails to get sent users are only informed after 5 days. I would like to configure Postfix to send a mail after e.g. 4 hours that the delivery has failed and that the system will try to send the message for another 5 days.
Is this possible?
